وَلاَ تَقْفُ مَا لَيْسَ لَكَ بِهِ عِلْمٌ إِنَّ السَّمْعَ وَالْبَصَرَ وَالْفُؤَادَ كُلُّ أُولـئِكَ كَانَ عَنْهُ مَسْؤُولاً
[17:36]
And follow not that of which you have not the knowledge; surely the hearing and the sight and the heart, all of these, shall be questioned about that.
And pursue not that of which thou hast no knowledge; for every act of hearing, or of seeing or of (feeling in) the heart will be enquired into (on the Day of Reckoning).
(O man), follow not that whereof thou hast no knowledge. Lo! the hearing and the sight and the heart - of each of these it will be asked.
